Long combined with tempo. 30 minutes in, switched to 4:15 min/km for 10 minutes, then 4:05 min/km for 5 minutes. Needed a 2 and a half minute break before I did the final 5 minutes at 3:50 min/km, then finished the run. Definitely tough.

The ground was icy and snowy, but the pace was still pretty close to target pace.2x 3, 2, 1 minute with 90 seconds of rest, followed by 8x 30 on 30 off that got interrupted by a stoplight. About 10 minutes of cooldown running back to school.
